CZ118198A3 - Method of operating spraying fire extinguishing device and apparatus for making the same - Google Patents

Abstract

The pipeline system from the dry alarm valve (3) to the sprinklers is filled with compressed air. The alarm valve is held closed by pressure compensation on the air and extinguishing water side and opened when pressure drops on the air side. The pipeline system is rapidly ventilated by a pneumatic device and the dry alarm valve is rapidly opened by a separate pneumatic device. The quick opening for ventilating the pipeline system takes place before the rapid opening of the dry alarm valve. The rapid openings are undertaken by separate throttle stretches. This ensures that the throttling for the ventilation is greater than the throttling for opening the alarm valve. Diaphragm valves can be used to control the ventilation of the pipe system and the opening of the alarm valve.

Description

Method of operating a fire extinguishing spraying device and a device for carrying it out

Technology ........

The invention relates to a method of operating a fire extinguishing spraying device and a device for carrying out the same.

Existing ......... state of the art

Fire extinguishers are known. They are used in areas with a risk of freezing to prevent the pipe network of a fire extinguisher filled with extinguishing water from freezing. The compressor air network is preferably filled with compressed air under a pressure of 2.5 bar by means of a compressor. An alarm valve is arranged between the atomizer pipe network and the fire-extinguishing water line, the valve plate of which is kept closed while the pressure is equalized between the compressed air and the water pressure. If, in the case, the sprayer opens, the compressed air escapes from the sprayer pipe network and thus from the air chamber of the alarm valve. As a result of the high extinguishing water pressure, the valve plate is opened so that the pipe system up to the atomizers is filled with extinguishing water and then exits from the atomizers to extinguish the fire. By the time the extinguishing water exits the atomizers, the time in which the fire may spread is elapsed.

The essence ........ yynal, ezu

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device by means of which the atomizer pipe network is rapidly vented, thereby rapidly starting the atomizer to the full capacity of the extinguishing water.

• · · · · · · · · · · · · · · · · · · · · · · · ·

This problem is solved by venting the duct system and opening the alarm valve by means of separate pneumatic devices, wherein the quick opening for venting the duct system occurs before the rapid opening of the alarm valve.

This measure ensures that the extinguishing water reaches the sprayer more quickly and, in addition, the individual spray valve groups with the alarm valve can be enlarged in volume. The time delay of opening the pipe system and the alarm valve ensures that the extinguishing water flowing at a higher pressure prevents the opening of the quick venting system.

So far, it has been prescribed by the directives that the extinguishing water, after opening the sprayer, with the air part of the spray pipe system maximum 4 m ³ , will fill it within 2 minutes at the latest. .

If 60 s is not reached, the toaster must be split and a separate pop-up valve assigned to each smaller volume group.

The invention achieves that due to the faster venting of the pipe conduit system and the faster opening of the alarm valve, the volume of the valve group is increased and thus smaller alarm valves can be installed. The inventive method also reduces investment costs.
